RX 460 Constantly Crashing

My RX 460 keeps crashing in all the games I play. I've had this problem for quite a while but I always managed to do the downclock workaround for it, but lately not even downclocking works with newer drivers anymore as in newer games it crashes instantly or every 5 mins or so. I want to know if it might be a specific problem from my side, as I don't really want to RMA it because it takes about a month or two in my country due to slow service.
